Is it just the foam surrounds that are gone on the speakers? If so, you can replace them. This is a better option than replacing the woofers and will maintain the original sound of these speakers.
Just search the AR forum for instructions and suppliers of foam. You will also find suppliers who will refoam your woofers. One of the forum regulars named Carl also re furbishes speakers.
